Block Parameters

Channel vector

Enter numbers between 1 and 8 to select the digital output lines
used with this port. This driver allows the selection of individual
digital output lines in arbitrary order. The number of elements defines
the number of digital lines used.

For example, to use all of
the digital outputs for one port, enter

[1,2,3,4,5,6,7,8]

Number the lines beginning with 1 even if this board manufacturer
starts numbering the lines with 0.

Reset vector

The reset vector controls the behavior of the channel at model
termination. Enter a scalar or a vector that is the same length as
the channel vector. If you specify a scalar value, that setting is
replicated over the channel vector. If you specify a value of 1,
the corresponding channel is reset to the value specified in the initial
value vector. If you specify a value of 0, the
channel remains at the last value attained while the model was running.

Initial value vector

The initial value vector contains the initial values (0 or 1)
of the output channels. Enter a scalar or a vector that is the same
length as the channel vector. If you enter a scalar, that value is
replicated as the initial value over the channel vector. The channels
are set to these initial values between the time the model is downloaded
and the time it is started.

Sample time

Enter the base sample time or a multiple of the base sample
time (-1 means sample time is inherited).

PCI slot (-1:autosearch)

If only one board of this type is in the target computer, enter -1 to
locate the board.

If two or more boards of this type are in the target computer,
enter the bus number and the PCI slot number of the board associated
with this driver block. Use the format [BusNumber,SlotNumber].

To determine the bus number and the PCI slot number, type:

tg = slrt;
getPCIInfo(tg, 'installed')
